Thanks for the bug report. I tried your pattern and input on the latest trunk,
and matched /^S/ 100000 times to your input. The JIT runtime was 0.16 sec, the
interpreter was 1.14 sec.
Am I see right that you use PCRE-8.33? That is a bit old revision, and several
improvements were added since then (e.g. 'S' has three lowercases, and matching
such letters was improved recently). Furthermore your input is not a valid UTF8
stream, and the matching behaviour is not defined in such cases.
Would it be possible to dump the input of pcre_exec calls in grep? I suspect
something is bad ('size' argument for example) with some input buffers.
